Lab drug test Question

    Does anyone know the cutoff levels for cannabis detection used in labs? I took an at home Wally world drug test and passed, with a very light line. It said that it's cutoff level was at 50 ng/ml. I have to go to a lab and take a drug test for court and I want to make sure I don't fail it.

    If you have a faint line on a store bought test, that's a for sure fail on any other drug test. Faint line means you have weed in your system

    I Just took a drug test today. Got kind of freaked out and started googling like a mad man. These are some of the results I found. I am positive I have passed, but I won't know for sure. I have taken 2-3 puffs on 3 different occasions over a 2 month period. The last time I smoked was 9 days ago. The test was sent to a lab, to be tested in accordance with DOT Rule 49 CFR. Most labs test at an initial of 50 ng/ml, upon confirmation of TCHA or THC-COOH Metabolite, the cutoff is then lowered to 15 ng/ml. Keep in mind that metabolites vary from day to day as well, this means you can test negative one day, and positive the next, vice versa. A way to decrease those chances are dilution of the urine. DO NOT test with urine from the opposite sex. According to the CDC, they test for levels of creatine, which are higher in males. Also, as nice of an idea they may be, don't waste your money on detox or synthetic urine. Use clean urine from a donor of the same sex. They key to all detox remedies, are diluting the metabolites. Some information here on Metabolite levels over a certain period of time, according to dosage, and frequency of use. I have yet to find any information of the sort on these types of forums, but if there already may be, could the moderators move this to the correct section? Thanks and Good Luck.
